Chuck Dachis's book, Radios by Hallicrafters, shows a picture of the R-274D/FRR, on page 59. You can clearly see the plate marking on the front. His claim is that the SX-73, R-274/FRR, and R-274D/FRR were virtually the same receiver. No mention on any mechanical filters. R-274A - SP-600-JX-1, and -JX-12 R-274B - SP-600-JX6, -JX-35 R-274C - SP-600-JX-14. -JX-26
